So far so good but on one of the 8 that I ordered and it was the last one in the hardest spot, I couldnt get the plug wire on the threaded part. It looked like someone at the factory must have had them in a pair of vicegrips and damaged the threads. Fortunately I had a set of small files and I was forced to clean/repair the damaged threads with these files. If I didnt have a flight the next day I may have tried a return but I was out of time. This is my first Tempest Plug purchase so I hop this one inst indicative. The other 7 were fine.

As just one data point, Ive noticed that these Tempest plugs are lasting longer than the Champion plugs they are replacing in my TSIO-520-R engine. Specifically, the Champion plugs are failing the resistance test about 100-200 hrs sooner than the Tempest plugs.

I like Tempest plugs in general as they tend to have better resistance values than Champions. However, the wrenching on tempest plugs are lower on the plug than Champions and this presents a problem when utilizing spark plug gasket CHT probes. There is interference between the wrenching and the wall of the counterbore for the spark plug on Lycoming engines. I have had to utilize a champion plug in that instance.

My first experience with Tempest spark plugs.
Upon receiving 12 urem40E spark plugs I checked resistance in each plug, they were all in specifications (500 ohms to 2,500 ohms for new plugs).
The lowest reading was 745 ohms and the highest was 1445 ohms, most of the plugs were around 1,325 to 1,345 ohms.
The plug gaps were all within specifications (.015 to.021).
I regapped all plugs (.015 to .018) and installed them in my Cessna 172 with a Continental o300 engine and they are all working fine so far (2 hours).
The Champions I took out had about 500 hours on them and all were within resistance specifications and all were within erosion tolerances and all were serviceable spark plugs.
If the Tempest plugs match the Champions performance, I will probably stay with the Tempest plugs due to the $10 price difference per plug ($120 total savings).

Works good, doesn’t foul even on bottom side of new cylinders with all that oil and junk in there while it’s wearing in.

I previously installed these in the lower plugs in an IO-540 engine to eliminate lead fouling. When the standard plugs in the tops needed replacing I upgraded to the Tempest fine wire plugs. The engine now runs noticeably smoother and the mag drops are minimal. I also noticed a drop in EGTs during takeoff. I recommend these spark plugs.

I bought the fine wire spark plug. To put in the bottom of my cylinder 3. Although the compression still reads 71 it seems to pump oil on that bottom plug. I have only put 4 hours on it so far. But performance seems to be the same as the massive one. I change oil and rotate plugs every 25 hours. I’ll let you know.

I like the quality and performance of the
Tempest Spark Plugs best. My last set were the Tempest Massive Electrodes that I switched to from the Champion Brand because of radio noise which went away with the Tempest Plugs. My current set for my
RV9A are the Tempest Fine Wire Plugs. They too are radio quiet and give great performance.

I replaced my defective Champion plugs with these, and they work great.
Although I hear that Champion has fixed their resistor problems, their denial of a problem (and silence on their fix for it) have made me a Tempest fan!

Great spark plug! I rarely have to replace these before they’re worn beyond spec. I highly recommend tempest spark plugs

I replaced six lower plug on TIO 540. The plugs prior to replacement were new massive plugs, however it was prone to lead fouling after less than 10 hours of flight. I lean it aggressively but unforgiving lead has set plug #4 & #6 foul up. The fine wire in my belief is a must on larger lycoming or continental engine.
Highly recommend the fine wire plugs, price is worth it. In my opinion it will pay for itself.
I am a Tempest convert now.

There are 12 spark plugs x 2 engines in a Seneca. Had Champions before replacing all the plugs with these winners.
No hard starts, no fouling and they look very cool with the stainless bodies.
The bonus is lower cost to buy and better fuel economy.

I've had fine where plugs in my Grumman Cheetah 0320 for about two years, they really work well and I always get the same mag drop with the upper or lower plugs. While they work perfectly, the exterior of the plugs corroded excessively. I mentioned this to Brian Cox at the Tempest booth at Sun n fun, he said for a short while they had an issue with their plating vendor. I sent him some pictures and the date codes, and I just received a completely new set of plugs! This type of customer service is remarkable-I will remain a staunch Tempest customer.

Plane runs well so far. Had to regap a few plugs out of the box. Quality control by Tempest?? Lost confidence in Champion after their spark plug resistance issue and magneto point redesign. Hopefully Tempest wont go the same way with their quality control.

Great spark plugs but with a significant flaw. The wrenchings (flat six sided) on Tempest spark plugs are cliser to the firing end of the plug than on Champion plugs. On some Lycoming engines this causes interference of the wrenching with the hard lead of spark plug gasket CHT probes with the counterbore of the the cylinder head. For my customers utilizing CHT spark plug gasket thermocouples I cant utilize Tempest plugs due to this design flaw.

I purchased this plug to replace an existing plug that lost the centre electrode. I am relieved that this happened on the ground shortly after startup as the engine ran extremely rough and it would have been way too exciting to have this happen during climb out.
